RO/DI

So I just bought a new rodi unit and it says on it 25 gpd.. But it comes out way faster than that!? So should I slow it down or is that a suggestion so I don't over use the filters ??

Are you sure your not looking at the waste water output? It flows faster than the pure water does.

Red is pure water. It runs much slower than the dump water. I run the discharge hose into my garden.

Your unit may have a flush valve on the RO unit. I use that to help maintain the membrane. I do it every few months for a half hour.

I don't see a flush valve.. Is there any other way to do that.. And I've heard ppl talk about being able to test this Water and make sure it's pure and the membrane is still working, how do I do that and how often is it necessary to change the filters and membrane!?

You need to get a cheap TDS meter so you can check the condition of your filters. EBay is a good source.
